Representative William Lacy Clay Jr. (D., Mo.), whose district includes the city of Ferguson, warned that tensions in the area may reignite if a transparent and thorough investigation doesn’t take place of the death of Michael Brown, who was shot by a police officer earlier this month. With demonstrations have gotten more peaceful in recent days, Face the Nation host Bob Schieffer​ asked Clay if he thought Brown’s funeral on Monday might prompt some protesters to return to the violence seen earlier.

“I’m more concerned if we do not get to the truth and get to what actually happened and bring justice to this situation, then there’s going to be a problem in the streets,” Clay said. He promised Brown’s parents that he would work to bring federal resources to investigate the case as well.
